Subject: [PATCH v3 2/2] drm/vc4: hdmi: Remove vc4_hdmi_encoder

The vc4_hdmi_encoder struct was used exclusively to cache the value
returned by drm_detect_hdmi_monitor() in order to avoid calling it
multiple times.

Now that drm_detect_hdmi_monitor() has been replaced with
drm_display_info.is_hdmi, there is no need to have an extra struct.

Remove vc4_hdmi_encoder.
